Standard implementation of
IUndoManager.
It registers with the connected text viewer as text input listener and
document listener and logs all changes. It also monitors mouse and keyboard
activities in order to partition the stream of text changes into undo-able
edit commands.
Since 3.1 this undo manager is a facade to the global operation history.
The usage of
IAdaptable in the JFace
layer has been approved by Platform UI, see: https://bugs.eclipse.org/bugs/show_bug.cgi?id=87669#c9
